Fort Laprairie

Fort Laprairie was a French colonial fortification built between 1687 and 1689 on the western bank of the St. Lawrence River following a military design. The structure had a trapezoidal shape and was positioned as a defensive stronghold against external attacks.

The fort was established in 1687 by Gédéon de Catalogne following Robert de Villeneuve's design and served as a protective post during early colonial conflicts. It played a key role during armed hostilities until 1713 when its strategic importance declined.

The fort served as a French military hub that protected trade routes and settlements spreading along the St. Lawrence River. The streets of La Prairie still follow the trapezoidal layout that the original fortification established.

No visible remains of the fort exist at the site today, but the location offers views across the St. Lawrence River. The place is easily reached from the town and blends well into the existing street layout.

The site gained notice for a military victory against English militia in August 1691, which demonstrated the strength of the French defensive system. This battle helped secure French control over the region even though the fort was later abandoned.
